Selling Point Descriptions 4-1-1. 3 modes of operation The Model DH 30PC provides 3 functions, "Rotation and striking", "Rotation only" and "Striking only". Thus, the Model DH 30PC is applicable to light-duty chiseling and grooving in concrete. 4-1-2. Optimum drilling mechanism for fastest speed The drilling speed is the fastest up to 20 mm (at concrete), as the Model DH 30PC/DH 30PB has great striking energy owing to the optimum design of the rotation speed, striking frequency and the weight of the striker. 4-1-3. A highly reliable mechanism for prevention of idle hammering The Models DH 30PC and DH 30PB are equipped with a mechanism that slides the tool retainer to prevent idle hammering. When the drill bit is pressed against the concrete surface, the striker is shifted to the striking position to start striking. When the drill bit is moved off the concrete surface, the striker is shifted forward to open the air hole so that air pressure within the air chamber no longer changes even with reciprocating movement of the piston, bringing the hammering action to a stop. Thanks to the highly reliable mechanism for prevention of idle hammering, the operability and the durability are improved. --- 2 ---
4-1-4. Variable locking mechanism The Model DH 30PC is equipped with a variable locking mechanism that allows the angle of a tool such as a cold chisel or a cutter to be rotated conveniently to 36 individual positions in relation to the work in the "Striking only" function mode. 4-1-5. Soft-touch grip for easier handling The double-layer molded handle consists of a plastic resin base covered with a soft plastic layer to ensure a soft touch and firm, non-slip grip of the handle. 5.

7. PRECAUTIONS IN SALES PROMOTION In the interest of promoting the safest and most efficient use of the Model DH 30PC/DH 30PB Hammer Drill by all of our customers, it is very important that at the time of sale the salesperson carefully ensures that the buyer seriously recognizes the importance of the contents of the Handling Instructions, and fully understands the meaning of the precautions listed on the Caution Plate attached to each tool. 7-1. Handling Instructions Although every effort is made in each step of design, manufacture and inspection to provide protection against safety hazards, the dangers inherent in the use of any electric tool cannot be completely eliminated. Accordingly, general precautions and suggestions for the use of electric power tools, and specific precautions and suggestions for the use of the Hammer Drill are listed in the Handling Instructions to enhance the safe, efficient use of the tool by the customer. Salespersons must be thoroughly familiar with the contents of the Handling Instructions to be able to offer appropriate guidance to the customer during sales promotion. 7-2. Caution Plate The Model DH 30PC/DH 30PB unit is provided with a nameplate which lists basic safety precautions in its use. Carefully ensure that the customer fully understands and follows these precautions before using the tool. (1) For the U.S.A. and Canada (2) For Australia, New Zealand, China and India 7-3. Grease Replacement The striking portion and the speed reduction portion of the Model DH 30PC/DH 30PB respectively use different types of grease. Grease replacement is required if the unit is disassembled for maintenance or o-rings become damaged or worn as described in 7-4. The striking portion uses special grease. If the striking portion (inside the cylinder case and crank case) is disassembled, thoroughly remove all of the old grease from each part. On reassembly, insert 30 g (1.1 oz) of new grease into the crank case (connecting rod side) and insert 10 g (0.4 oz) into the cylinder case (outside the cylinder). Do not exceed the designated amount of grease. Excessive grease insertion may cause reduced striking performance. The speed reduction portion (inside the gear cover) uses Hitachi Motor Grease No. 29 (Code No. 930035). The proper supply volume is 30 g (1.1 oz). Never use the striking portion special grease in the speed reduction portion. Special grease would leak into the motor portion and cause subsequent trouble. --- 10 ---
7-4. O-Ring Replacement The O-rings (mounted on the striker and the piston) are extremely important to ensure adequate sealing of the air pressure. Although the o-rings are made of special rubber to give them a long service life, they do nonetheless become worn, and should be replaced with new ones periodically depending on frequency of use of the tool. With average use, it is recommended that the o-ring be replaced at least every six months to ensure maximum effectiveness. 8.

Rotational Transmission The rotation of the armature is transmitted to the third pinion through the second gear and clutch (B) in the case of the Model DH 30PC. In the case of the Model DH 30PB, the rotation of the armature is transmitted to the third pinion through the second gear. Then the rotation is transmitted from the third pinion through the third gear and the key to turn the cylinder. The rotation of the cylinder is transmitted to retainer sleeve (B) through the steel ball of the slip clutch mechanism, and to retainer sleeve (A) through the needle of the idling-proof mechanism. The rotation of retainer sleeve (A), which is key-connected to the inserted drill bit by means of two key rails, is transmitted to the drill bit. 8-2. Striking Operation The rotation of the armature is transmitted to the crank shaft through the first gear and clutch (A). Then the rotation is transmitted to connecting rod, which in turn cause the piston to reciprocate inside the cylinder. As the piston reciprocates, the changing air pressure inside the air chamber between the piston and the striker causes the striker to continuously strike against the end of the second hammer. At the same time, the air-cushion effect within the air chamber absorbs the impact of the second hammer. Should the air escape from the air chamber, the air-cushion effect would cease, and the impact energy would not be absorbed. Accordingly, the o-rings mounted on the striker and piston play an extremely important role in sealing the air within the air chamber. --- 12 ---
8-3. Idling-proof Mechanism When the drill bit is released from concrete surface, the second hammer and retainer sleeve (A) move to the position illustrated in Fig. 4, and the striker moves out of striking position. When this occurs, the air holes are opened and the pressure within the air chamber remains unchanged even though the piston continues to reciprocate, thereby preventing striking operation. Retainer sleeve (A) Second hammer Striker Air hole Air chamber Piston Fig. 4 8-4. Slip Mechanism The slip mechanism structure is described below with reference to Fig. 5. The rotation of the cylinder is transmitted to retainer sleeve (B) through six steel balls. Steel balls in holes provided on the cylinder are pressed on outer of retainer sleeve (B) by spring (A) through the pushing ring. When an excess torque is exerted on the drill bit, steel balls are slipped out retainer sleeve (B) against the load of spring (A) to allow idle of the cylinder. With this arrangement, the clutch slips when a violent torque is applied to the tool as with the drill bit contacting steel wire within the concrete, protecting the operator from jerking or being violently thrown around.

8-5. Sealed and Dust-proof Construction The crank case and cylinder case are sealed by four o-rings, and two oil seals which serve to prevent leakage of the grease, as well as to prevent dust and dirt from entering the mechanism. The drill bit chuck portion is protected by a rubber front cap to keep out dust and chips. Front cap O-ring Crank case O-ring O-ring O-ring Oil seal Oil seal Cylinder case Fig. 6 8-6. Speed Control The variable speed control switch permits free change of the rotation speed and striking force. When drilling in fragile materials, pull the switch trigger gently for low rotation speed and striking force to achieve optimum results. --- 14 ---
8-7. Function Mode Mechanism The change lever of the Model DH 30PC permits quick and easy changeover among the "Rotation and striking", "Rotation only" and "Striking only" functions. Also the change lever of the Model DH 30PB permits changeover among the "Rotation and striking" and "Rotation only" functions. When operating the change lever, be sure to continue pressing the pushing button. Change lever Rotation only Change lever Rotation only Pushing button Pushing button Striking only Rotation and striking Rotation and striking (a) DH 30PC Fig. 7 (b) DH 30PB (1) Rotation and striking Adjust the change lever to "Rotation and striking". On one hand, the rotation of first gear, which is transmitted from the armature, is transmitted to clutch (A) by matching with claws of the first gear and of clutch (A), and to the crank shaft via the spline of clutch (A) and of crank shaft. Then the rotation is transmitted to connecting rod, which in turn cause the piston to reciprocate inside the cylinder. On the other hand, in the case of the Model DH 30PC, the rotation of second gear, which is transmitted from the armature, is transmitted to clutch (B) by matching with claws of the second gear and of clutch (B), and to the third pinion via the oval of the second gear and of the third pinion. Then the rotation is transmitted from the third pinion through the third gear and the key to turn the cylinder.

Third gear Piston Cylinder Connecting rod Key Crank shaft Third pinion Clutch (A) Second gear First gear Armature (b) DH 30PB Fig. 8 (2) Rotation only Adjust the change lever to "Rotation only". On one hand, clutch (A) is moved above by the pin of the change lever, and engagement between clutch (A) and the first gear is released. So the first gear idles on the crank shaft, and striking is stopped. On the other hand, in the case of the Model DH 30PC, the second gear engages with clutch (B), and so the rotation is transmitted to third pinon for "Rotation only" function. In the case of the Model DH 30PB, the rotation of the armature is always transmitted to the third pinion through the second gear in which the third pinion is press-fitted.

On one hand, clutch (B) is moved above via the shift plate by the pin of the change lever, and engagement between clutch (B) and the second gear is released. So the second gear idles on the third pinion, and the rotation of third pinion is stopped. Clutch (B) on the third pinion is engaged with the lock plate to lock the turn of tool. Thereby, the tool can be carried out in the arbitrary direction. On the other hand, the first gear engages with clutch (A), and so the rotation is transmitted to crank shaft for "Striking only" function.

8-8. Tool Retainer The opening where the tool is inserted is covered with the front cap made of rubber to prevent dust from entering inside. When the tool is inserted, the steel ball fits in to the matching groove on the tool to lock it in place and prevent it from coming off. The key rails transmit rotating torque to the tool. The grip is held forward by the holder spring. To mount the tool, pull the grip back to compress the holder spring. Then the steel ball moves outward. While turning the tool, push it until it makes contact and is fully inserted. Then release the grip so that it moves forward and fixes the tool. To remove the tool, simply pull the grip back fully and pull the tool out. 9.
